NBA Commissioner David Stern Stern instituted a system this season that fined players for flopping after video review, but believes there needs to be more punishment.

"We're never going to get rid of it," Nowitzki said recently, according to The Dallas Morning News. "But you got to limit it. It's part of sports. It's part of winning. Some people are smart and do a little extra thing to kind of sell the call. To me, that's part of sports."

Only five players were fined $5,000 in the regular season for flopping.

"You don't want the obvious ones, the really, really bad one," Nowitzki said, according to the newspaper. "I think we'd love to get rid of those. But if somebody really does get shoved or hit a little bit, just to sell it a little for the referees so it does get the call, I don't have a problem with that. I think that's part of the game."
